To all whom it may concern.'

Be it known that I, ALEXANDER Q. NASH, a citizen of the United States,residing at Kansas City, in the county of Jacksonand YState of Missouri,have invented certain new and useful Improvements in Horizontal Oil-Burners, of which the following is a` full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use thesame.

My invention relates to burners and especially to that general class ofburners which may be adapted or constructed for the burning offuel oilssuch as kerosene, gasolene, crude oil and other heavy hydrocarbon oils;this application being a continuation in part of applicants co-pendingapplication Serial No. 141877, liled JanuaryV 11, 1917, Patent No.1225994, granted May 15 1917.

The presenty invention provides a burner of the above described classwhich is of such construction that it may readily replace the usualgrate structure in the common furnace or cook-stove or may even beinserted above the grate. l

It further provides a burner whichis back-lire proof by reason of theshape and location of the mixing and distributing chambers.

An added and most important feature of this burner is that a start-ingtrough is made integral andco-extensive with the sides of the burner and`vertically above that is located a retort tube having a U-shape withsubstantially parallel legs, each'end of the tube being so assembled inconnection with the burner appurtenances that, when it is desired toclean the retort tube it is only necessary to open eachend of the saidjretort tube in order to obtain complete access to the interior thereof.i

Other objects `and features will `appear from the detailed descriptionof a specific and preferred form of the burner illustrated in theaccompanying drawing in which:

Figure 1 is a top plan View of a .burner of the horizontal typeconstructed according to the fundamental principles of my presentinvention.

Fig. 2`is an end view of the burner shown in Fig. 1; u

Fig. 3 is a section View ,on the line 3-3of Eig, L,

rate baille. plate 4dividing the cylindrical i interior "of theshellinto a lower mixing chamber `B and an upper distributing chamber'C; the said mixing chamber B has formed integrallytherewith a gasinjector tube 5 extending fairly well into the interiorthereof'anddelivering toward the concave surface ot'Y the hemisphericalend 6 or' the shell A, a plug 7 closes the core hole in theendof saidshell.` p y p Along opposite sides of the shell A and cast integrallytherewith in such location as to be entirely out of the combustion zoneof the iburner are starting troughs 8 and 9 which Aare preferablyiilledwith some noncombustible absorbent Vmaterial 10 such as asbestoswicking.

At itsV rearA end the'burner shell A has a spotlluponwhich is mounted abracket 12 and additional supports 13 are provided at the forward end ofsaid shell. The bracket 12 and supports 13 serve to mount a retort tubeD of substantially Ufshape and having legs 14 and 15 which areco-extensive with thefstarting troughs `8 and 9 respectively. The legs14 and 15 are supported vertically abovethe starting troughs 8 and 9 andat suiiicient height so as to embrace the margin of the zone ofcombustion and lie partially within the edges thereofas shown in Fig. 3.Thesaid legs 14 and 15 contain `very thin wire strands 1G which may bepulled outV of the endsof" the legs in order to clean. the latter. TheseWire strands serve to break up the particles of hydrocarbon as itbecomes volatilized and gasified in the retort tubes. l

At the forward end of the shell A is mounted a damper box E which isprovided with a rectangular opening 17 which, toward its end, mergesinto a round opening 18 registering with the mouth of the fuel injectortuloef.r The forward end of `the which closes Athe lend of the damperbox E shell A also carries the supports 13 for the retort `tube D.V Thebottom of the opening 17'V slopes slightly as shown at 19 so as to feedany residual unvaporized oil toward the burner instead .of .permittingit lto drip outside and also, to insure against dripping, an upturnedlip 20 is provided.U Hinged to the ydamper box E on lugs 21 is a damper22 and is v adjusted bya screw 23 working in a threadedJ member 34 onthe side fof ,the

v damper box and having its end 35 Vengaging an .ear 3.6 vonthedamper272 andthus, as the Y adjusting screw 23 is turned bythe thumb knob 37Athe zdamper leaf 3S-is mov'edto or away from the opening in the damperbox thereby Lgiving .more zor less air y'draft as the case .may be. MThedamper box E. is aper- -tured as at 89 and the damper leaBS is slottedas. at.v 40 for affte'rset forth.

InV order to clean the retort tube it is only necessary to remove theplug 43 and T 45 when the wires 16 may be withdrawn from the legs 14 andl5 or, if desired only plug 43 may be removed and air pressure appliedat 46 will blow all sediment y.or carbon accumulation out of the retort`tube. Y

While, in the foregoing, I have described a specific form of Athe.present invention .it is nevertheless to be understood that, inpractice, I may resort to. such practical modifications as fall withinthe scope of the appended claims; also, it iste be noted that my burnerisy not strictly confined to use with liquid fuels.
